AGENT ANTISLIPPING DEVICE FOR SKIS The present invention relates to a ski accessory and, more particularly, to an antislipping device for skis, enabling the skier to climb hill while maintaining the skis in parallel condition and flat on the snow.

Already known antislipping devices for skis must be installed at the rear end of the skis, whereby the device is pressed against the snow with insufficient force to effectively prevent slipping and, when not in use, cannot be stored in a completely out-of-the-way position, thereby always constituting a hinderance to normal skiing movements. Moreover, the skier has often difficulty in reaching the device and placing the same into operative position without detaching his ski boots from the skis. 2

Accordingly, the general object of the invention resides in the provision of an antislipping device for skis, which obviates the above-noted disadvantages.

A more specific object of the invention resides in an antislipping device for skis which can be installed on the ski, close to the ski binding, preferably just behind the ski boot heel binding, so that the antislipping member will exert maximum pressure on the snow or ice, and in which said member is confined on the upper face of the ski when not in use, so as to be in a completely out-of-the-way position, in no way hindering normal downhill skiing.

Another object of the invention resides in the provision of a device of the character described, which can be fitted on skis of various widths and/or thicknesses.

Another object of the invention resides in the provision of a device of the character described, which in no way affects the snow engaging the underface of the ski.

Another object of the invention resides in the provision of a device of the character described, in which the antislipping member itself is positively prevented from displacement when in operative or inoperative position.

Another object of the invention resides in the provision of a device of the character described, which is easily moved between operative and inoperative position by the skier himself while wearing his skis.

Another object of the invention resides in the provision of a device of the character described, which is free of dangerous projections, which is inexpensive to manufacture and which is easily installed on the ski. The foregoing and other objects of the present invention will become-more apparent during the following disclosure and by referring to the drawings, in which:

FIG. 1 is a partial side elevation of a ski with a ski boot attached to the same and the antislipping device of the invention installed on the ski and showing the gripping member in position;

FIG. 2 is a side elevation of the antislipping device with the antislipping member in operative position and shown mounted on a portion of a ski seen in side elevation;

FIG. 3 is a view similar to that of FIG. 2, but with the cover FIG. 4 is a top plan view of the arrangement of FIG. 3;

FIG. is a cross section, taken a long line 5-5 of FIG. 3;

FIG. 6 is a view similar to that of FIG. 2 but showing the antislipping member in inoperative position; and

FIG. 7 is a cross section taken along line 7-7 of FIG. 6.

In the drawings, like reference characters indicate like elements throughout.

Reference numeral 1 indicates the central portion of a ski, on the upper face 2 of which is secured in conventional position a toe binding part 3 and a heel binding part 4 for clamping a ski boot 5 on the ski.

The antislipping device of the invention is generally shown at 6 and is preferably mounted on the ski 1 just behind the heel binding part 4.

Device 6 comprises a support in the form of a plate 7 adapted to be secured to the ski upper face 2 by means of screws 8, said plate 7 having spaced paralleled upwardly extending transverse walls 9 running across the long axis of the ski.

The side edges 10 of plate 7 extend close to the side faces 11 of the ski I. An antislipping member 12 is swingably connected to the support or plate 7 for movement across a side face 11 of the ski between an inoperative position overlying the upper face 2 of the ski and an operative position extending across the underface 13 of the ski.

Antislipping member 12 consists of a plate 14, of rectangu lar or square shape, from one face of which extend cross ribs IS. The other face of plate 14 is lined with a layer 14 rubberlike material. The ribs are in the shape of flanges adapted to run transversely to the long axis of the ski. In the example shown, there are four cross ribs 15 arranged in spaced parallel relationship and coextensive with the width of plate 14.

Cross ribs 15' provide the antislipping means and are directed towards the snow, that is away from the underface of the ski when the member 12 is in operative position.

The means for swingably connecting the member 12 to the support or plate 7 comprise rods 16 and 17 respectively running through and attached to the sidewalls 9 of plate 7 and running through and attached to the cross ribs 15 of plate 14. The two rods 16, 17 are respectively parallel to the side edge 10 of plate 7 and the side edge of plate 14.

Endless bands 18, made of rubber or the like elastic material, surround the rods 16 and 17.

Plate 14 is provided along its edge opposite to rod 17 with flanges I9 directed away from cross ribs 15 and adapted to engage a side face 11 of ski 1. Plate 14 has also a central hooking flange 20 disposed between the two flanges l9 and directed in the same direction as cross ribs 15.

Elastic hooking means are provided for engaging hooking flange 20. The hooking means comprise a toggle lever system provided with a hook at the outer end thereof. The toggle lever system consists of a rigid lever 21 having its inner end pivoted at 22 to a bracket 23 secured to plate 7. The outer end of rigid lever 21 carries a cross pin 24, to which is attached one end of a plurality of extensible coil springs 25 running side by side and having their other end attached to a cross pin 26.

A book 27 is attached to cross pin 26 by means of a looped flexible rope 28. Hook 27 is detachably engageable with booking flange 20 of the antislipping member 12.

The device further includes a cover 29 pivotally mounted on support 7 and movable between open and closed position. The cover 29 is pivoted at 30 to a bracket 31 secured to the wall 9 closer to heel binding part 4 and its outer end has a spring clip 32 engageable with beaded edge 33 of the opposite sidewall 9 to resiliently retain the cover in closed position.

The cover 29 further has a lifting tab 34 to facilitate opening thereof. Cover 29 may be spring urged into open position. Flanges 35 depend from the opposite side edges of the cover 29 and terminate short of the plate 7 and extend between the walls 9 in the closed position of the cover. The cover has slots 36, one of which is partially shown in FIG. 5, adjacent the flange 35 opposite rod 16 and adapted to receive the flanges 19 in the inoperative position of the antislipping member 12.

The device of'the invention operates as follows: i

In its operative position, member 12 extends across the underface 13 of ski I with its flanges l9 engaging and overlapping a side face 11 of ski 1. Member 12 is maintained in this position in an elastic manner by means of elastic bands 18, as shown in FIG. 5, extending across the opposite side face of ski l and stretched against the same and by means of hook 27 engaging the hooking-flange 20 extending over the other side face of the ski and maintained taut by the tension springs 25. Layer 41 prevents damage to the underface of the ski and prevents longitudinal slipping of member 12 relative to the ski.

It will be noted that springs 25 constitute the outer leg of a toggle lever system, the rigid lever 21 constituting the inner leg of said system. In the closed position of the lever system, the line of action of the force exerted by springs 25 on cross pin 26, extends below pivot 22 of lever 21, whereby the toggle lever remains in closed position.

It is easy to open the toggle lever system by pivoting rigid lever 21 upwardly, as shown in dot-and-dash lines in FIG. 5,,to

thereby release hook 27 from hooking flange 20. In the operative position of the toggle lever system and of the antislipping member 12, cover 29 is closed to protect and enclose the toggle lever system. Rope 28 and elastic bands 18 extend outwardly of the cover through the openings between cover flanges 35 and support plate 7. To replace the antislipping member 12 in inoperative position, cover 29 is open; lever 21 is pivoted upwardly and the hook 27 released from hooking flange 20. The coil springs 25 contact and the lever 21 is pivoted downwardly back against plate 7. The gripping member 12 is swung through 360 about elastic bands 18 from a position under the underface of the ski to a position fitting on top of plate 7 and overlying the folded toggle lever system, as shown in FIG. 7. The cover 29 is then closed and slots 26 of said cover receive the upwardly extending locating flanges 19 of antislipping member 12, as shown in FIGS. 6 and 7.

The toggle lever system is confined between the two central cross ribs of anticlipping member 12 and the latter is confined between the walls 9 of plate 7 and cover 29 and its flanges 25. Moreover, because flanges l9 engage slot 36, any

rattling of the member 12 is prevented.

The reverse operation is effected to secure antislipping member 12 in operative position.

it is apparent that the device of the invention can be fitted on skis of different widths and thicknesses, due to the elastic swingable connection between the member 12 and the support plate 7 and also due to the fact that member 12 engages only one of the side faces 11 of the ski in the operative position of member 12.

The device can be installed close to the ski boot binding, preferably behind the same, whereby great pressure can be exerted by member 12 on the snow or ice, resulting in effective antislipping action of the device.
